2020 MAZDA MODEL 6 Owner's Manual (in English)

Selective Catalytic Reduction (SCR) System(SKYACTIV-D 2.2)
The SCR system is designed to reduce nitrogen oxide (NOx) in the exhaust gas and purify
the exhaust gas by injecting it w ith Diesel Exhaust Fluid (DEF).
WA R N I N G
Be careful not to allow the DEF to run out. If the DEF completely runs out, the SCR system will
not operate normally.
When the remaining DEF is low, a message is displayed on the multi-information display, and
the SCR warning light turns on/flashes.
Refer to Selective Catalytic Reduction (SCR) System Indications on page 4-231.
In this case, consult an Authorized Mazda De aler. If DEF needs to be replenished, add DEF
following the specified procedure.
Refer to Diesel Exhaust Fluid (DEF) Replenishment on page 6-33.
NOTE
DEF needs to be replenished periodically according to the scheduled maintenance
information.
Normally, the vehicle can be driven about 12,000 km (7,500 miles) before the DEF needs
to be replenished. However, it may need to be replenished earlier depending on the
driving and environmental conditions (such as putting a high load on the engine while
driving or driving the vehicle at high altitudes).
The sound of the SCR system operating may be heard from the area under the vehicle,
however, this does not indicate a problem.
▼ Selective Catalytic Reduction
(SCR) System Indications
As the remaining amount of Diesel Exhaust Fluid (DEF) lowers, t he SCR system notifies
the driver using the fo llowing indications.
The vehicle speed may be restric ted for a while even if the warning light turns off after
replenishing the DEF. To cancel the vehicle speed restriction i mmediately, switch the
ignition OFF after the warning li ght turns off and then switch the ignition ON again.
